Comment # 2 on bug 1159276 from Stakanov Schufter

Some more insight: I do not get a traceback otherwise but, starting from
terminal gives some insight. I am using gajim with tor but the issue does
appear also in installations without this particularity. 

>From CLI

I put this to confirmed as this is now present in three different machines with
TW and as well with Leap 15.1. Apparently in Leap since the latest updates that
came in yesterday or today.
